[ic] Limit number of results returned (not just a [more] question ;)

[Bryan D Gmyrek]

Hi,

As you know one can use ml=50 to control how many results are shown on the
results page.  While looking for info on my question I found only info on
this sort of problem...
But does anyone know how to actually limit the number of results returned
by a standard scan search to, say 500?
For example:

I search for blue on my site and it returns 50,000 results.
No one wants to click next for 50,000 items.
So I display a note instead that says 'Your search returned 50,000
items, please refine your result'
This will only happen if, say more than 300 results are returned
(otherwise they see more...)

What I'd *like* is to do like G00gle and only fetch the first, say 300
results and give the option to do more to see those (instead of just
flatly saying no, you can't see more).

Anyone know how to do this?

Thanks,
Bryan
